這篇文章主要為大家詳細介紹了python獲取版本信息的方法與第三方庫,文中的示例代碼講解詳細,具有一定的借鑒價值,感興趣的小伙伴可以了解下

當前版本信息

獲取當前的版本信息如下：

def get_python_base_version():
    """獲取python版本信息"""
    version_dict = {
        "Python版本": sys.version,
        "Python解釋器路徑": sys.executable,
        "版本詳細信息": sys.version_info,
    }
    return version_dict

獲取所有第三方庫

獲取全部的第三方庫：

def get_python_site_packages():
    # 查看Python的包搜索路徑
    logger.debug("Python包搜索路徑:")
    _packet_path: dict = {"第三方庫": {}, '搜索路徑': sys.path}
    try:
        # 獲取所有已安裝的包
        distributions = list(importlib.metadata.distributions())
        distributions.sort(key=lambda dist: dist.metadata["Name"].lower() if dist.metadata["Name"] else "")
        # 獲取site-packages路徑
        site_packages_paths = []
        try:
            site_packages_paths = site.getsitepackages()
        except:
            site_packages_paths = [p for p in sys.path if 'site-packages' in p]

        user_site_packages = site.getusersitepackages()
        all_third_party_paths = site_packages_paths + [user_site_packages]

        displayed_packages = set()  # 避免重復顯示

        for dist in distributions:
            package_name = dist.metadata["Name"]
            if not package_name or package_name in displayed_packages:
                continue

            displayed_packages.add(package_name)
            # 直接檢查dist的路徑屬性
            dist_location = None
            try:
                # 對于某些版本的importlib.metadata，可以直接獲取路徑
                if hasattr(dist, '_path'):
                    dist_location = str(dist._path.parent)
            except:
                pass
            # 如果無法直接獲取，嘗試通過文件推斷
            if not dist_location and dist.files:
                for file in dist.files:
                    if file.parent:
                        file_path = str(file.parent)
                        for third_party_path in all_third_party_paths:
                            if third_party_path in file_path:
                                dist_location = third_party_path
                                break
                    if dist_location:
                        break
            # 如果在第三方包路徑中，則顯示
            if dist_location and any(tp_path in dist_location for tp_path in all_third_party_paths):
                _packet_path["第三方庫"][package_name] = dist_location
    except Exception as e:
        logger.error(f"獲取包信息時出錯: {e}")
    return _packet_path
